Complete Health
Build a broader picture. A broader proposed panel, including HbA1c, a full blood count and additional nutritional and hormonal markers.
Know what you’re choosing.
The widest of these proposed options. It needs a venous blood sample taken by a professional, rather than a home finger-prick kit.
HOW IT FITS YOUR SHIFT
A broader panel can support a wider clinical conversation about blood sugar, blood health, nutrition and hormones. It is not automatically the better choice: the tests should fit the question you are trying to answer.
Complete is the name of this panel. It cannot check for every condition or replace a clinical assessment.
What’s in the picture.
Open an area to explore the markers shown in this guide. Some markers appear in more than one group; these groups are not a count of separate tests.
CholesterolBlood fats linked to heart health, alongside your food, movement and weight goals.
The balance of fats in your blood helps inform a heart-health assessment. High cholesterol often has no symptoms, so how you feel is not a reliable guide to your level.
In your SHIFT: The scales are only part of the story. Put cholesterol alongside your waist, blood pressure, food and activity when discussing longer-term health.
NHS: cholesterol testing ↗The proposed markers
- Total cholesterol
- HDL cholesterol
- HDL as a percentage of total
- LDL cholesterol
- Non-HDL cholesterol
- Triglycerides
Liver functionLiver-health markers that matter when considering weight, alcohol and metabolic health.
These markers can help flag liver problems. Fatty liver can be linked to excess weight and metabolic health, while alcohol and other causes also need consideration. Blood results alone do not provide the whole diagnosis.
In your SHIFT: If weight, waist size or drinking is part of your SHIFT, liver health belongs in that conversation too. Results need interpretation rather than an assumption that every change is down to your weight.
NHS: fatty liver and metabolic health ↗The proposed markers
- Alanine aminotransferase (ALT)
- Albumin
- Alkaline phosphatase (ALP)
- Bilirubin
- Gamma-glutamyl transferase (GGT)
- Globulins
- Total protein
Kidney function essentialsHelps assess filtering, alongside the wider picture of blood pressure and diabetes risk.
Creatinine is used to estimate how well your kidneys filter waste, reported as eGFR. This is part of a kidney assessment; repeat blood tests or urine testing may also be needed.
In your SHIFT: Kidney health connects with blood pressure and diabetes. These markers can add useful context to a wider health review; they are not a standalone hydration score or proof that all is well.
NHS: assessing kidney function ↗The proposed markers
- Creatinine
- Estimated glomerular filtration rate (eGFR)
- Urea
HbA1cA view of average blood sugar over roughly two to three months, rather than a single moment.
HbA1c can help assess longer-term blood sugar and is used in diabetes diagnosis and monitoring. A healthcare professional needs to interpret it in context, and it is not suitable for every situation.
In your SHIFT: This connects directly with the metabolic side of the journey: looking beyond body weight to blood sugar, food, activity and the care you may need.
NHS: blood sugar and HbA1c ↗The proposed markers
- HbA1c
Vitamins & mineralsSelected nutrients that add context to blood health, tiredness and the food you are managing to eat.
For example, vitamin B12 and folate are important for healthy blood cells, and deficiencies can contribute to tiredness. The listed markers check selected areas; they do not measure the overall quality of your diet.
In your SHIFT: Eating less should still mean eating well. If your appetite or food choices have changed, this is useful context for a nutrition conversation. Results do not automatically mean you need supplements.
NHS: B12, folate and blood health ↗The proposed markers
- Adjusted calcium
- Albumin
- Calcium
- Ferritin
- Active vitamin B12
- Folate (vitamin B9)
- Magnesium
- Vitamin D
Cardiovascular risk markerHigh-sensitivity CRP measures an inflammation marker; it does not explain the cause on its own.
CRP is a non-specific marker of inflammation. The high-sensitivity measurement needs interpretation alongside your health history and other findings, rather than being treated as a diagnosis.
In your SHIFT: It is another piece of a wider clinical conversation, not a score for how healthy you are or proof that a food, exercise plan or medicine is working.
NHS laboratory: CRP and its limitations ↗The proposed markers
- High-sensitivity C-reactive protein (hs-CRP)
Iron statusLooks at iron stores and availability, which can be relevant when investigating tiredness or anaemia.
The proposed iron profile includes several markers rather than relying on a single number. Abnormal results need interpretation and, where appropriate, investigation of the cause.
In your SHIFT: If low energy is getting in the way of everyday life or activity, a proper assessment matters. Do not assume tiredness is simply lack of fitness or start iron supplements on that basis.
NHS: blood tests and anaemia ↗The proposed markers
- Ferritin
- Serum iron
- Total iron-binding capacity (TIBC)
- Transferrin saturation
- Unsaturated iron-binding capacity (UIBC)
Free testosterone & SHBGAdds context to testosterone availability, rather than turning one hormone number into a diagnosis.
SHBG is a protein that binds sex hormones. Free testosterone and related calculations can contribute to a fuller hormonal assessment when interpreted appropriately.
In your SHIFT: The aim is a better clinical conversation about persistent symptoms. These results do not automatically establish a deficiency or a need for TRT.
NHS laboratory: SHBG and testosterone ↗The proposed markers
- Free androgen index (FAI)
- Free testosterone
- Sex hormone-binding globulin (SHBG)
Thyroid functionHormone checks that can help investigate tiredness or weight changes, with clinical context.
Thyroid hormones help regulate how your body uses energy. An underactive thyroid can cause tiredness and weight gain, but these symptoms have many possible explanations.
In your SHIFT: Persistent low energy or unexplained weight changes deserve more than a guess about motivation. These checks can support a clinical investigation without assuming the thyroid is the cause.
NHS: thyroid symptoms and testing ↗The proposed markers
- Free thyroxine (T4)
- Thyroid-stimulating hormone (TSH)
- Triiodothyronine (T3)
CortisolA hormone measurement affected by sample timing and clinical circumstances, not a day-to-day stress score.
Cortisol follows a daily rhythm, and the collection time matters when interpreting a result. A single measurement cannot explain how stressed you feel or diagnose the cause of fatigue.
In your SHIFT: Sleep, routine and stress still deserve attention in their own right. This result needs a specific clinical question and the right interpretation, rather than a promise to explain everything.
NHS laboratory: cortisol and sample timing ↗The proposed markers
- Cortisol
Full blood countLooks at blood cells, including checks that can help investigate anaemia and tiredness.
A full blood count measures blood-cell numbers and characteristics. It can help investigate conditions such as anaemia, but it does not give an overall immunity rating.
In your SHIFT: When low energy is affecting daily life or making activity harder, the cause matters. Blood-count findings sit alongside your symptoms and history, not a judgement about effort.
NHS: full blood count and other blood tests ↗The proposed markers
- Basophils
- Eosinophils
- Haematocrit
- Haemoglobin
- Lymphocytes
- Mean corpuscular haemoglobin (MCH)
- Mean corpuscular haemoglobin concentration (MCHC)
- Mean corpuscular volume (MCV)
- Mean platelet volume (MPV)
- Monocytes
- Neutrophils
- Platelets
- Red cell count
- Red cell distribution width
- White cell count
A professional blood draw.
Nurse home visit
A professional venous blood sample taken at home. Home collection appointments are currently unavailable through SHIFT.
Follow the instructions supplied for your exact test. Preparation and collection timing depend on the panel and will be confirmed before you order.
A result needs context.
These tests measure the markers listed, not every aspect of your health. Your symptoms, history, medicines and the circumstances of the sample matter.
Persistent or worrying symptoms deserve a conversation with your GP. Do not wait for a private test if you need medical care.
Understand what happens afterwards.
No stock available today. Tests and collection appointments cannot currently be ordered or booked through SHIFT.
The final service information will also set out collection support, insufficient samples, repeat kits, turnaround expectations, cancellation and refunds.
